| 摘要: |
| 针对工业用的超音速等离子体发生器的特点，采用无水冷单孔皮托管快速扫描法测量超音速等离子体射流的动压，用喷管出口平面埋静压管的方法测量静压，从而得到超音速等离子体射流的马赫数。为了对此测量方法进行验证、比较，利用一些可以方便测得的量，通过一些普通定律计算出超音速等离子体射流的马赫数，二者比较，相对误差小于10%。 |

| Abstract: |
| Be dead against the characteristic of supersonic plasma generator used in the
industry, in this paper used foramina singular and non-water-cooling Pitot tube to measure
dynamical pressure of supersonic plasma jet by fast scan. Used hydrostatic pressure tube
that is buried in nozzle exit surface to measure hydrostatic pressure. Thus Mach number of
supersonic plasma jet has been obtained. In order to verify check and compare the measure
method, we had been computed Mach number of supersonic plasma jet. Making experimental
data contrast with results of calculation, fractional error less-than 10%. |
